Female electrical contact

Abstract

The invention relates to a one-piece female electrical contact ( 1 ) which is cut and folded and which comprises, longitudinally, a rear area for connecting to an electrical conductor, a protective cage, which consists of a floor ( 4 ), two lateral walls ( 5, 6 ) and at least one ceiling element, and, on the front, a termination which is in contact with a complementary male contact. Said contact termination consists of at least one elastic contact blade ( 8, 9 ) comprising a blade which is connected to the rear of at least one ceiling element ( 22 ) and which extends towards the rear before folding.

1. A cut and bent, one-piece, female electrical contact comprising, in the longitudinal direction, a rear zone of connection to an electrical conductor, a protective housing comprising a bottom ( 4 ), two side walls ( 5 ,  6 ) adjacent to the bottom ( 4 ) and bent back along a longitudinal axis, and at least one top element ( 22 ,  23 ), this electrical contact comprising, on a front, a contact terminal, which is situated in the housing, to a complementary male contact, this contact terminal being formed by at least one spring contact tine ( 8 ) provided with a terminal part ( 10 ) pointed towards the front of the contact, characterized in that said spring contact tine is constructed from a small strip that is joined to a rear of the top element, this small strip extending, prior to bending, towards the rear and, after bending, towards the front, wherein after bending the contact tine including the terminal part is orientated generally perpendicular to the bottom. 
   
   
     2. The female electrical contact according to one of  claim 1 , further characterized in that the tine has, in the region of its connection to the top element, a first bend ( 45 ) along an axis that is perpendicular to a longitudinal axis of the contact, a first section ( 45 ) extending away from the top element, a second biased bend ( 47 ) forming a second section ( 48 ), and a third bend ( 49 ) defining a rear part of a spring section ( 31 ) that joined to a convex section ( 32 ) of contact to a complementary contact. 
   
   
     3. The electrical contact according to  claim 2 , further characterized in that the second section ( 48 ) includes an edge supported against the top element ( 23 ). 
   
   
     4. The electrical contact according to  claim 1 , further characterized in that the contact includes means ( 25 ,  26 ) of retention in a contact carrier box. 
   
   
     5. The electrical contact according to  claim 4 , further characterized in that these means include at least one opening ( 25 ) introduced into a side wall of the contact. 
   
   
     6. The electrical contact according to  claim 4 , further characterized in that these means include at least one tab ( 26 ) constructed on one of the side walls of the housing. 
   
   
     7. The electrical contact according to  claim 1 , further characterized in that the contact includes a retainer flap ( 20 ) for pretensioning the terminal part ( 10 ) of the tine, this flap being bent back from a front of the side wall ( 5 ) with respect to the tine, the tine comprising, on its part, in front of a contact zone, a section of support against the flap. 
   
   
     8. The electrical contact according to  claim 7 , further characterized in that the flap includes anchoring lugs ( 60 ,  61 ), the bottom and the top element containing receiving holes ( 62 ,  63 ) for these lugs. 
   
   
     9. A cut and bent, one-piece, female electrical contact comprising, in the longitudinal direction, a rear zone of connection to an electrical conductor, a protective housing comprising a bottom, two side walls adjacent to the bottom and bent back along a longitudinal axis, and at least one top element, this electrical contact comprising, on a front, a contact terminal, which is situated in the housing, to a complementary male contact, this contact terminal being formed by at least one spring contact tine provided with a terminal part pointed towards the front of the contact, characterized in that said spring contact tine is constructed from a small strip that is joined to a rear of the top element, this small strip extending, prior to bending, towards the rear and, after bending, towards the front, wherein the bending of the small strip forming the tine comprises a twisting. 
   
   
     10. A cut and bent, one-piece, electrical contact comprising, in the longitudinal direction, a rear zone of connection to an electrical conductor, a protective housing comprising a bottom, two side walls adjacent to the bottom and bent back along a longitudinal axis, and at least one top element, this electrical contact comprising, on a front, a contact terminal, which is situated in the housing, to a complementary male contact, this contact terminal being formed by at least one spring contact tine provided with a terminal part pointed towards the front of the contact, characterized in that said spring contact tine is constructed from a small strip that is joined to a rear of the top element, this small strip extending, prior to bending, towards the rear and, after bending, towards the front, wherein the contact further includes at lease one pair of the tines ( 8 ,  9 ) and one pair of the top elements ( 22 ,  23 ), each of the tines of the pair of tines being joined to one top element of the pair of top elements. 
   
   
     11. A cut and bent, one-piece, electrical contact comprising, in the longitudinal direction, a rear zone of connection to an electrical conductor, a protective housing comprising a bottom, two side walls adjacent to the bottom and bent back along a longitudinal axis, and at least one top element, this electrical contact comprising, on a front, a contact terminal, which is situated in the housing, to a complementary male contact, this contact terminal being formed by at least one spring contact tine provided with a terminal part pointed towards the front of the contact, characterized in that said spring contact tine is constructed from a small strip that is joined to a rear of the top element, this small strip extending, prior to bending, towards the rear and, after bending, towards the front, wherein the contact further includes a stiffening device in a linking region between a rear zone of connection and the housing, the stiffening device being formed by arches ( 70 ,  71 ) joining a top part of the side walls ( 5 ,  6 ) and an extension of the bottom adjoining the crimp tabs ( 50 ,  51 ) of an electrical wire.
